I pulled off the valve stem while taking off my rear tire. The tube is a super duty moose racing tube. The way the stem came out it looks like you could just rubber cement it back in place and go. Has anyone done that before?

I know it's just a tube but that joker is thick. It maybe a 20 dollar tube or something.

Lasrecustoms. If you ride any kind of street I would not use a super duty tube. The stem go bad also they are hard to install out in the field. I been having luck with a med duty tube. Leave that tube to a full time dirt bike. No you can't rubber cement it back it wont hold. The tube will flex in the tire sometimes when you remove a tire you will even see twist makes on tubes to.

I run an HSR42 Mikuni as well. Which needle are you running? I use a j8-8ddy01-97 (center clip), on advice from XRs Only, but I'm still not convinced I'm quite "there" yet. Next step is some dyno tuning time I think. I currently have a 20 pilot, 150 main, & 45 leak.

Laser, you must have the most creative spelling of anyone I've ever read. According to Mark Twain, you have a very interesting mind indeed.

I would be real curious to get the carb all perfectly dialed in... I'll be happy to send it to you to play with and see if you like it... I was told by a guy at Sudco that it is the way to go over the Keihin, but I don't really know for sure???? I had an FCR pumper as well as the Flat slide in the past. I really have not had this carb all dialed in to see if I really like it or not. I have several rides but wanted to drive the FOKKER off a cliff until I discovered the cracked boot. I have used RTV and sealed the crack, Hopefully I can get some saddle time soon and see if I have the problem solved. I would like to have a Keihin pumper to swap back and forth to play with. I need to port the new boot and play... I may pick up a Keihin from Sudco and compare, then sell the one that places second in my liking....

I was thinking it was the Keihin I had, but after review it was the Mikuni... I had them reversed mentally.... I seem to do that more and more and more???

I have my head off to correct some oil burning issues. What should I inspect on the valves to make sure they are good to go when I reassemble?
The valves are not suspected to be the culprit, no smoke at start up, just when revved. I'm guessing I can use some seafoam to remove the carbon deposits on the valves?
Thanks

The manual gives a method to check the valves.
The side to side movement is checked.
A wire wheel is usually used to remove carbon from the valves.
You may wish to have the seats re-ground.

But I gota ask, how much oil was it using?
Did you check all the breather stuff first?
Mine uses 4 OZ per 200 miles and there is no smoke at all.

I did check the breather from the case to the airbox, disconnected it even, still, lots of smoke. The bike is de-smogged and uncorked. As for oil usage, I have no idea how much it used, I never checked, after leaving a smoke screen everywhere I went, I just topped it off and tore it down.
